Effective Ecology Seeking Success in a Hard Science

Effective Ecology Seeking Success in a Hard Science

Ecology is one of the most challenging of sciences with unambiguous knowledge much harder to achieve than it might seem. But it is also one of the most important sciences for the future health of our planet. It is vital that our efforts are as effective as possible at achieving our desired outcomes. This book is intended to help individual ecologists to develop a better vision for their ecology – and the way they can best contribute to science. The central premise is that to advance ecology effectively as a discipline ecologists need to be able to establish conclusive answers to key questions rather than merely proposing plausible explanations for mundane observations. Ecologists need clear and honest understanding of how we have come to do things the way we do them now the limitations of our approaches our goals for the future and how we may need to change our approaches if we are to maintain or enhance our relevance and credibility. Readers are taken through examples to show what a critical appraisal can reveal and how this approach can benefit ecology if it is applied more routinely. Ecological systems are notable for their complexity and their variability. Ecology is as indicated by the title of this book a truly difficult science. Ecologists have achieved a great deal but they can do better. This book aims to encourage early-career researchers to be realistic about their expectations: to question everything not to take everything for granted and to make up their own minds. | Effective Ecology Seeking Success in a Hard Science

VLSI Architectures for Modern Error-Correcting Codes

VLSI Architectures for Modern Error-Correcting Codes

Error-correcting codes are ubiquitous. They are adopted in almost every modern digital communication and storage system such as wireless communications optical communications Flash memories computer hard drives sensor networks and deep-space probing. New-generation and emerging applications demand codes with better error-correcting capability. On the other hand the design and implementation of those high-gain error-correcting codes pose many challenges. They usually involve complex mathematical computations and mapping them directly to hardware often leads to very high complexity. VLSI Architectures for Modern Error-Correcting Codes serves as a bridge connecting advancements in coding theory to practical hardware implementations. Instead of focusing on circuit-level design techniques the book highlights integrated algorithmic and architectural transformations that lead to great improvements on throughput silicon area requirement and/or power consumption in the hardware implementation. The goal of this book is to provide a comprehensive and systematic review of available techniques and architectures so that they can be easily followed by system and hardware designers to develop en/decoder implementations that meet error-correcting performance and cost requirements. This book can be also used as a reference for graduate-level courses on VLSI design and error-correcting coding. Particular emphases are placed on hard- and soft-decision Reed-Solomon (RS) and Bose-Chaudhuri-Hocquenghem (BCH) codes and binary and non-binary low-density parity-check (LDPC) codes. These codes are among the best candidates for modern and emerging applications due to their good error-correcting performance and lower implementation complexity compared to other codes. To help explain the computations and en/decoder architectures many examples and case studies are included. More importantly discussions are provided on the advantages and drawbacks of different implementation approaches and architectures.
